Title: Field electron emission element and manufacture thereof
Inventor: KOMATSU HIROSHI
IPC: H01J1/30
Filed: 1990-11-20
Abstract: PURPOSE:To improve the uniformity of electric characteristics by making an insulating layer contain, as its material components, the material component of a cathode electrode and an insulating impurity component which converts this material component into an insulating material. CONSTITUTION:Si3N4 films are piled up at the position where the cathode electrode is formed of an n-type Si single crystal substrate 1 to form a diffusional mask in a shape of truncated cone with a diameter of 5000Angstrom  by photoetching. Next, oxygen is diffused in a portion without the mask 6 by the thermal oxidation method to form an SiO2 insulating layer 3, and the portion of Si remains because oxygen does not invade into the lower portion of the mask 6, so that the portion becomes a cathode electrode 2; when steam oxidation is made, the portion of the electrode 2 conically projects. Then, a gate electrode layer 4' of Mo is formed on the insulating layer 3 by the sputtering technique and the mask 6 is removed by the dry etching method, etc., to make a gate electrode opening 4a. Moreover, the insulating layer 3 is opened to expose a cathode electrode with an HF buffer liquid. As a result, the shortest distance between the cathode electrode 2 and the gate electrode 4 is approximately 2700Angstrom  and also their mutual dispersion is lessened.

Title: Automatic equalization system
Inventor: FUKUDA EISUKE
IPC: H04B3/04
Filed: 1987-12-14
Abstract: PURPOSE:To enhance carrier reproduction at a reception side by performing the pre-equalization of a transmission signal by feeding back each tap coefficient value of an automatic equalizer at the reception side to a transmission side and deciding the tap coefficient of a pre-equalizer at the transmission side. CONSTITUTION:At the reception side, a radio signal from the transmission side, after receiving and demodulating, is converted to a digital signal, and the digital signal is equalized by a digital automatic equalizer 3 by using the tap coefficient obtained by the signal, and output is generated. Meanwhile, the tap coefficient used in a reception signal at the equalizer 3 is returned to the transmission side by using a coefficient returning means 4. At the transmission side, an input digital signal is pre-equalized by using a returned tap coefficient at the pre-equalizer 5 provided at the front stage of a transmission means 1, and an equalized signal is made into an analog signal, and is converted to a modulation signal, and furthermore, it is delivered after being converted to the radio signal. Therefore, the carrier reproduction can be enhanced at the reception side by performing the pre-equalization even in status where distortion is generated on a transmission path.

Title: Semiconductor laser module
Inventor: MICHIKOSHI HISATO
IPC: G02B6/42
Filed: 1992-10-30
Abstract: PURPOSE:To eliminate the variation in characteristics even when a ferrule is repeatedly attached and detached, to facilitate the assembly, and to secure small characteristic dispersion and nearly the same mechanical strength as the conventional by inserting a transparent body which has nonparallel front and rear surfaces between the ferrule and a lens in a manner of not in contact with the ferrule tip. CONSTITUTION:The transparent body 10 which has the nonparallel front and rear surfaces is inserted between a ferrule fiber and the lens in a manner of not in contact with the tip of the ferrule fiber. The projection beam of a semiconductor laser 1 is condensed by the lens 2 and then refracted by the transparent body 10 having the nonparallel front and rear surfaces to slantingly impinge on an end surface of an optical fiber. Consequently, reflected light on the end surface of the optical fiber 3 returns in a direction different from the semiconductor element 1. Reflected light on the front surface of the transparent body 10 also returns in a direction different from the semiconductor laser element 1. Therefore, reflection points increase in number, but any reflected light does not return to the semiconductor laser element 1, so that the deterioration in modulation characteristics due to a reflected noise is reduced.

Title: Steering lock device for automobile
Inventor: KUROKI SHIGENOBU
IPC: E05B83/00
Filed: 1990-11-20
Abstract: PURPOSE:To reduce the number of parts, and to reduce the size of a body by forming a mechanism of a steering shaft which is not locked until a key is drawn out, only out of a key lever stored in a cylinder latch internal cylinder. CONSTITUTION:When a rotor 3 is pushed in by a key which is not indicated in the drawing, against the energizing power of a spring 14, the engagement between a protrusion 3b of a semi-circle cam 3a and the engagement surface 8a of a slider 8 is cancelled. When the rotor 3 is turned to a lock position, an engagement protrusion 7a of a key lever 7 is engaged with a guide groove 12. When the key is drawn out of a key inserting hole 6, the key lever 7 is oscillated by the energizing power of the spring 14, and is buried in the rotor 3, while the engagement between the engagement protrusion 7a and the guide groove 12 is cancelled, and the rotor 3 is moved forward. The engagement between the slider 8 and the outer peripheral surface of the rotor 3 is thus cancelled, and the slider 8 is energized in the lower direction by a spring 10. As a result, a lock pin 9 connected to the slider 8 is protruded, and a steering shaft is locked thereby into a state that it is not turned at all.
